Papua New Guinea–Bougainville: Three-quarter threshold requirement unlikely to be met during August vote
On 9 June, Papua New Guinea's Parliament adopted a sessional order establishing the process for debating and voting on ratification of the 2019 Bougainville independence referendum. The order requires a three-quarter parliamentary majority to ratify the result. Approval would initiate a phased transition to independence, while rejection would maintain Bougainville's autonomous status. Parliament is expected to vote on ratification by 30 August. The decision followed the presentation of a public consultation report by the Bipartisan Parliamentary Committee on Bougainville Matters. Bougainville President Ishmael Toroama has since urged Bougainvilleans to remain calm, while Vice President Ezekiel Masatt has criticised the three-quarter threshold and reaffirmed that Bougainville's position on independence is non-negotiable.
Assessment: The ratification vote on 30 August is a critical milestone. The three-quarter threshold requirement is unlikely to be achieved, particularly as PNG's Prime Minister James Marape has not explicitly endorsed independence and several Members of Parliament have expressed concern about potential implications for other regions. Political lobbying is likely to intensify ahead of the vote, and isolated violent incidents involving Bougainvilleans living in mainland PNG are likely. Failure to ratify the referendum will almost certainly increase political tension between PNG and Bougainville, while heightening public frustration in Bougainville. In this event, both parties will very likely seek guidance from the Melanesian Agreement framework around further negotiations.
